To all whom z't may concern:

Be it known that we, FRED LICHTENBERG and MICHAEL M. MoCARTiiY, citizens of the United States and residents of Yonkers, Westchester ounty, and State of` New York, have invented certain new and `useful Improvements in Building Constructions, of which the following is a specification.

This invention relates particularly to wall constructions and the application of the trim for the doors, windows, baseboardsand the like.

The objects of the invention are to construct the trim in complete units of such form` that' they may be readily mounted and applied to the wall structure and be` rigidly and permanently secured in place, so as to reinforce and'become an integral part of the wall or building.

These objects are attained in our invention by means. of certain novel features of construction, combination and relation of parts, as will appear in the course of the 1n conjunction with the accompanying drawings forming part thereof and wherein we have illustrated the invention embodied in some of its simplest and most practical forms.

Figure 1 in the drawings referred to is a broken perspective view of a wall constructed in accordance with our invention, and showing our special door, window and baseboard trim as in use.

Figure .2 is a vertical sectional view of the top of the window casing, on substantially the plane of line 2 2 of Figure 1.

Figure 3 is a similar sectional view of the sill portion of the casing, substantially on the plane of line 3 3 of Figure 1.

Figure 4 is a .horizontal sectional view of the side portion of the window frame, on substantially the ure 1.

Figure 5 is a horizontal sectional view,

illustrating the adjoining end portions oftwo of the slabs of which the wall is made.

Figure 6 is a sectional viewmof the door frame, on substantially the plane of line 6 6 of Figure 1.

' Figure 7 is a vertical sectional View of the lower portion of an interior wall showing the baseboards applied thereto.

Specification of Letters Patent. Patented Mar, Application iled June 10, 1921. Serial No.'476,448.

following specication, which is t o be read -usually applied as the plane of line of Fig-- Figure 9 is a detail view showing Athe insideconstr'uction of the baseboard unit.-

Figure 10 is a broken detail of a transombar construction, andY Figure 11 a section of same on line 11 11. ln constructing the wall, we preferabl use the wall slabs disclosed in our co-pen ing application, Serial #411,163, consisting of pre-cast slabl units of a suitable "concrete or cementitious material such as we haveyindicated at 10 -in Figure, arranged vertica lly in edge-to-edge relation, each having wire-netting reinforcements l1 therein, i

doubled over and protruding at one edge of the slab at 12, andv having the free ends protruding from the opposite side of the slab at 13, the projecting folded reinforcement 12 .at the edge of one slab being fitted between the projecting edges 13 on the adjoining slab, so as to in eliect mesh the adjacent slabs together. n

When the slabs are constructed with the corrugated or otheraircell forming members 14, as in the application referred to, these air cell forming members are preferably inclined to the general fiat plane of the slab, as we have indicated in Figure 5, so that they will overlap in the wall to provide a continuity of the air cell structure.

After the slabs4 have been set up in the relation described, the joints between the slabs are completed by applying cement which is usually troweled on, as l-have indicated at 15.

The door trim and the window trim are wall is built up. In

other words, the slabs are set up edge to edge until the point is reached where a window or door is to be located and then the door or window casing is abutted against thelast slab and other slabs are built on around such casing.

These casings are each formed hollow, usually of relatively thin but stili sheet me al and they are secured in place by filling them with cementitious material which,

as it hardens, ing to the adjoining wall structure.

-Considering first the window casing, it

will be seen from Figures 2, 3 and 4 that the reinforces and bonds the oassame consists of a hollow shell 16 shaped to provide one or more internal shoulders or beads 17 and having edge flanges 18 spaced at the outer open side of `the frame to fit over the edges of the adjoining slabs. In

ether over t e ad]o1n1ng y bolts or other suitable usua secured to edges of the slabs fastenings` 19.

In the top of the frame (Figure 2), slots are provided either at one or both sides of thewall to enable the bonding and rein forcing cement being poured intolthe frame.

Thusafter the frame -is setup andthe slabs are positioned about the same, 'the cement` in liquid form 1s poured in at the vtop of the casing so that it fills up the entire interior ofthe casing, as wel have shown at 21, and

` overflows to a certain extent about the'edges so as to form a bond with the edge portions of the surrounding slabs, as we have indicated particularly at 22 in Figure/4. At this filling hardens, it will beseen that the casing is made practically solidand a uni with the wall structure in which it is set.

If desired, jambs 23 vof wood or the like may be set in' the frame for the fastening of the hinges or other hardware, the hollow' casing being for the purpose constructed witha recess or pocket 24 rto receive the jamb. -1 v f The door frame is constructed similarly to the window frame in that it is made up o a hollow shell 25, open at its outer edgesand shaped about its interior to provide a stop shoulder or flange 26. This frame may be secured in place in the same manner as the window frame, as by having bolts. 27 passed through the edge flanges 28 and the intervening material of the slab over which the .frame is fitted.

Along the top and at the outside or the in side o r at both faces, the frame is provided with slots or openings 29 to receive thecementitious filling and bonding material which is poured in after the door frame has been set in the walland the slabs built up therearound.

The frames may be provided with suitable inserts positioned to be embedded in the concrete, as indicated at 30 in Figure 6, to receive bolts or other astenings for' door hinges and the like and if desired, `the frames .may4 be shaped vwith pockets 31 to receive felt or other packing strips 32.

The base board trim is also constructed as a hollow shell, as t shown particularly at 33 in Figure 7, being given any desired or; namental configuration and having openings 34 in the top flanges thereof to receive the cement lilling 35. Thisv filling flows along the interior of the baseboard, solidifying the same and bonding it to the slabs particularly at the joints between the slabs, itbeing evident from Figures 7 and 8 that the filling material will flow out at such joints about the wire mesh on the adjoining edges of the slabs.

In the several forms of trim shown, we

`have illustrated incach instance a shoulder or stonden as paviaaghgfeundsa for the plaster, stucco or other material.V

The shell oi the baseboard is Ishown as having a dependent flange 37 at'the top and anupstanding flange 38 at the bottom thereof to bear against the wall slabs and the inside view ofthe shell, Figure 9, shows how the .pouring openings l34 are preferably extended down into the upper flange, and how bondin openings 39 are provided in the lower ange 38. y

This invention, it will be seen, makes `it possible to build up a wall or other structure very quicklyout of standard stock units and the wall thus constructed becomes,` by

' the bonding and reinforcement of the parts,

practically a solid unit.

The hollow frame members provide the complete trim, including lintels, sills, stools, aprons, jambs and stops and when filled with the concrete, operate as solid reinforcements, bonding the various units of the structure.

It will be understood that the structure may be modified in various respects to meet diiierent building requirements. In the case of transom doors, for instance, the frame 'will be constructed to extend the full height from Hoor to ceilin as we haveindicated in Figure 10, so t at when the frame is filled with the solidified concrete, there will be two solid reinforced columns extending from Hoor to ceiling and tied together by the transom-bar 40 which being filled with concrete during the pouring operation acts as a tie to hold the columns solidly together. These columns may be internally vreinforced, if desired, by means of suitable mesh e'fabric or rods, as mdicated 'at 41, (Figure l1).

The window frames maybe constructed with grooves conta'ning packing strips similar to the doors, as indicated in Figures 2, 3 and 4.t The strips or wooden inserts 23 (Figures 2 and 4) may be placed inside the metal shells, as shown, or they may be seated in grooves at the outside of the shells, and we have shown in Figure 2 how grooves 42 may be formed along the upper edge of a frame to receive a pivot pin on the upper end of a section of a double' hinged door or window.

As many structural-changes may be made within the scope of our invention, wewish it understood that the terms used herein are employed in a description rather than in a limiting sense, except for such limitations as may be required by the prior art.

' What we claim is:

1. In building construction, slabs arranged in adjoining relation to form a wall with openings therein andframes fitted in said wall openings and consisting each of a hollow metal shell closed at the interior of the frame and having spaced flanges about 13o the exterior of the drinne eeeeiving between them the edge nortiens of the surrounding wall slabs, said danges overlying and secured in contact with the opposite faces of the received slabs to thereby close the slab-receiving opening about the exterior of the frame and the thus closed frame having' an opening or openings in the upper portion thereof for the admission o a liquid concrete which een be poured into the hollow frame to solidify the seine and bond it to the surrounding 'wall slabs.

2. The structure of claim 1 in which the wall slabs are constructed with overlapping bonding means at the adjoining edges there of which are entered Within the hollow shell of the iframe so that the lling also automatically elects the bonding together of adjeva cent slabs.

3. ln building construction, slabs arranged in edge to edge relation and pro= vided at their adjoining edges with overlapping bonding elements and building trim in the forni of ahollovv shell having an open side closed by the slabs and whereby the filling or@ eementitioue nieterial penned into seidv fiat slabs having cellular elements exxnidingtherethrough, inclined withl respect to the general flat plane of the slabs and projecting beyond the edges thereof.,

5, ln building construction, substantially flat slabs having eellular elements extending therethrough, inclined with respect to the general flat ple-ne of the slabs and projecting beyond the edges thereof and Wire mesh reinforcements embedded in the slabs having lapped portions and spaced free ends at opposite edges of the slabs.,

ln :witness whereof, We have hereunto set our hands this 6th day of dune, 1921. FRED LLCHTENBERG. hdlUli-UJL M. Mo.Gi/3i.lll-l-Zn
